ASTM E662-13, “Standard Test Method for Specific Optical Density of Smoke Generated by Solid Materials,” has just been released and is available from Document Center Inc. This new 24-page standard covers determination of the specific optical density of smoke generated by solid materials and assemblies mounted in the vertical position in thicknesses up to and including 1 in. (25.4 mm).
This new revision of the well established smoke test is used for construction, maritime and railway applications throughout the world. It is similar to the ISO 5659-2:2012 and BS 6401:1983. The 2013 Edition is the first revision of the ASTM E662 since 2009.
The test itself requires a smoke chamber. The test specimens are exposed to both flaming and nonflaming conditions. Then a photometric system with a vertical light path is used to measure the varying light transmission as smoke accumulates. The light transmittance measurements are used to calculate specific optical density of the smoke generated during the time period to reach the maximum value.
